The next 7 days
Tulsa, OKGrowing in Tulsa right now
- Tulsa's sandy-loam soil warms quickly but dries rapidly; water deeply in the morning to keep moisture around young bulbs without shocking them.
- The city's flat terrain allows cold air to settle overnight, so cover exposed garlic seedlings with floating row covers if temperatures dip near 5°F.
- Take advantage of Tulsa's mild fall weather to finish weeding vegetable beds now, as heavy spring rains haven't arrived yet.
- Avoid planting cool-season transplants immediately; wait for the first frost-free window in late March before moving tender crops.

Seasonal tips
- Finish harvesting cool-season crops like Daikon radish before temperatures drop too low.
- Plant cover crops or winter rye now to protect soil structure during the dormant season.
- Apply a thick layer of mulch around garlic plants to insulate bulbs from freezing ground.
Pest & disease watch
- Watch for onion thrips on emerging garlic leaves, which can cause silvering and stunting if untreated early.
- Monitor soil for cutworms that often target newly planted bulbs in Tulsa's open fields after rain events.
- Check seedlings for root maggots, a persistent issue in the region where moist spring soils favor larval development.
Watering this week
Water garlic lightly and only when the soil is dry, avoiding wetting the bulbs directly to prevent rot.
Store your freshly harvested Daikon radishes in a cool, humid place like a crisper drawer or sand-filled bin.
Tulsa gardening questions
3When is the safest date to plant garlic cloves in Tulsa?
You can sow garlic now through mid-October, but aim for early October when soil temperatures cool slightly. Planting too late risks bulbs not establishing before our average last frost on March 28th.
Can I transplant tomatoes or peppers this week in the Tulsa area?
No, wait until after April 15th to avoid freeze damage. The risk of hard freezes persists until late spring given our zone 7b classification and history of sudden cold snaps.
How often should I water my new garlic beds in October?
Water deeply once a week if rain is scarce, as Tulsa's fall weather can be dry and windy. Stop irrigation completely when leaves begin to yellow and retreat toward the base in November.
